HORSESHOE.

To all whom it may concern Be it known that I, ELMER K. POWELL, acitizen of the United States of America, and resident of Steubenville,county of J efferson, and State of Ohio, have invented certain new anduseful. Improvements in Horseshoes, of which the following is aspecification.

This invention relates broadly to horseshoes, and specifically to aremovable calk for horseshoes.

The primary object of the invention is to provide a detachablehorseshoe-calk and securing means whereby said calk is rigidlymaintained on the shoe against chance dis placement.

A further object within the contemplation of the invention is to providea calk and securing means therefor which is of extremely simpleconstruct-ion and which is consequently comparatively inexpensive tomanufacture. And a still further object is to provide a device of thecharacter mentioned which may be readily applied or removed by anyperson without removing the shoe from the horses foot.

WVith these and other objects in view, the invention finally consists inthe features of construction, arrangement of parts and combination ofelements which will hereinafter be fully described, reference being hadto the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a plan view of the under side of a horseshoe, showingthe invention applied to the toe and heels thereof; Fig. 2 is an edgeview of the same; Fig. 3 is a section on the line 4-4, Fig. 2, showingthe locking lever in calk-receiving position; Fig. 4 is a similar view,showing the lever in looking position; Fig. 5 is a sect-ion on the line55, Fig. 1; Fig. 6 is a detail perspective view of a calk; andFig. 7 isa similar view of the locking lever, detached.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several views1 indicates ahorseshoe of a common type, on the under face of, which and centrally ofthe toe portion is mounted a locking member comprising a substantiallycircular fiat body, or disk, 2 and an arm 3 integral with and in theplane of said disk. A rivet or stud 4, preferably integral with the disk2, is located centrally with respect to said disk and constitutes themeans whereby said lock- Specification of Letters Patent.

ing member is secured to the shoe, said stud being projected through theshoe and havilpg it; free end upset, as is clearly shown in Provided inthe body of the shoe on each side of and at a spaced distance from thehole provided for the stud 4 is a hole 5, said stud-hole and the holes 5being in alinement and in line with the direction of greatest lengthdesired for the calk to be applied. The disk 2 has two recesses 6provided in its peripheral edge at diametrically opposite points, saidrecesses, when the disk occupies one position, registering with adjacentportions of the holes 5 and conforming in size and contour to theregistering portions of said holes. Thus, when said disk occupies suchposition, studs 7 formed on the upper face of a calk 8 are readilyreceived in said holes, as is clearly shown in Fig. 3, said studs beingof a size and form to neatly fit said holes.

Provided in the upper face of the calk 8 between the studs 7 is asubstantially rectangular recess 9 whose depth corresponds substantiallyto the thickness of the disk 2 and whose length correspondssubstantially to the diameter of said disk, the studs 7 being slightlyundercut in the formation of said recess.

When the calk has been mounted on the shoe with the studs 7 in the holes5, as shown in Fig. 3, the locking member is rotated on the stud 4 as anaxis, the arm 3 being employed for effecting such rotation, to theposition shown in Fig. 4, thus carrying portions of the peripheral edgeof the disk into underlying relation with said studs 7, as is clearlyillustrated in Figs. 4 and 5. Thus the calkis locked in place.

The rivet or stud 4 has its free end drawn down to cause the disk tobind closely upon the shoe. Consequently, a sharp blow, or a series ofblows, applied to the arm 3 is re quired to move the locking member tolooking position; and, having assumed such position, the possibility ofchance retraction is remote. Further, since the calk may be releasedonly when the locking member is completely retracted, or occupies asingle one of infinite positions, the chance of the calk becomingreleased is extremely remote. One of the recesses 6 is preferablyprovided adjacent to one of the lateral edges of the arm 3 in order thatthe locking member may traverse substantially an angle of 90 in movingfrom unlocking position to the eX- treme limit of locking position.

The device may be employed bot-h upon the toe and heel portions of theshoe, as shown in Figs. 1 and 2, and the body of the calk may be of anydesired form.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a horseshoe having stud-receiving holes therein,of a calk seated on the under face of said shoe, said calk having studsfitted in said holes, and a substantially circular locking memberpivotally mounted on said shoe between said holes, said member when inone position allowing insertion and removal of said studs and when inother positions interlocking with said studs.

2. The combination with a horseshoe having stud-receiving holes therein,of a calk seated on the under face of said shoe, said calk having studsfitted in said holes, and a substantially circular locking memberpivotally mounted on said shoe between said holes, said calk having arecess formed therein in which said member is received, the ends of saidrecess extending partially beneath said studs, and said member having inits periphery recesses adapted to register with said holes when itoccupies one position.

3. The combination with a horseshoe having stud-receiving holes therein,of a calk seated against the under face of said shoe,

studs carried by said calk mounted in said holes, said calk having arecess in its upper face which partially undercuts said studs, and adisk pivoted on said shoe received in said recess and interlocking withsaid calk.

l. The combination with a horseshoe having stud-receiving holes therein,of a calk seated against the under face of said shoe, studs carried bysaid calk mounted in said holes, said calk having a recess in its upperface which partially undercuts said studs, and a disk having recessestherein mounted on said shoe and received in said recess in the calk ininterlocking engagement with said studs.

5. The combination with a horseshoe hav-- ing stud-receiving holestherein, of a circular disk pivoted to said shoe intermediate saidholes, said disk having oppositely disposed recesses therein whichregister with adjacent portions of said holes when the disk occupies oneposition, a calk having a pair of studs adapted to seat in said holesand having therein a disk-receiving recess whose opposite ends undercutsaid studs, said disk being adapted to inter look with said calk whenturned from the aforementioned position.

In testimony whereof I aflix my signature in presence of two subscribingwitnesses.
